s claims.

This invention relates to an attachment for a conventional type of floormop which attachvment is constructed for the purpose of wringing handleto an out-of-the-way position when not in use.

. Brieiiy described, the improved attachment comprises a sleeve slidablymolmtedon the shaft or handle, said sleeve being provided at one endwith an enlarged apertured cylinder into which the mop head is receivedwhen wringing the Water therefrom, said cylinder being provided atscription and drawings.

In the drawings:

Figure 1 is an elevation view showing the complete structure andillustrating the wringer pushed down to its operating or mop squeezingposition.

Figure 2 is a view similar to Figure 1 observing it in a direction atapproximate right angles to Figure 1.

Figures 3 and 4 are cross sections on the lines 3-3 and 4 4respectively, of Figure 1.

Figure 5 is an enlarged longitudinal detail sectional view showing alatch forming a feature of the invention.

Figure 6 is a view which may be said to be on the line 6 6 of Figure 2.

Referring now to the drawings by distinguishing reference characters, itwill be observed that the fabric mop proper is denoted by the letter A,this being attached to a back or head B which is in turn secured tothehandle or shaft C. The attachment and its appurtenances is denoted as aunit by the numeral 1. Broadly, this comprises a slide, and specificallythe slide includes a sleeve 8 which fits rather snugly, but slidably onthe shaft, said sleeve having a hand knob 9 adjacent its upper end forconvenient grasping and utilization. The sleeve merges into a taperedenlarged portion I 0 at its lower end which is substantiallyfrusto-conical and this joins to and is integral with an apertured shellor cylinder Il. This cylinder serves asa sort of receiver for the mop Awhen it is drawn up into thecylinder during the wringing or squeezingoperation.

The wringer rolls or rollers are indicated by the numerals I these beingpreferably externally corrugated and disposed in spaced parallelism, andthese rollers are mounted for rotation in opposed pairs of suitablydesigned carrier yokes or brackets I3. These brackets I3 are pivoted asat I4 on diametrically opposite sides of the lower end portion of thecylinder.

In a sense, the brackets or carriers I3 are in the nature of bell crankswith their adjacent ends pivoted together in overlapping form. The loweror outer end portions of the bell cranks are offset sufficiently to takecare of the length of the wringer roll I2. The opposed pairs of bracketsare held together through the instrumentality of coiled springs I4 whichare connected therewith. It is evident, therefore, that when the rollsare on opposed sides of the mop A, as illustrated in the drawings, bydrawing the mop upwardly therebetween the water is naturally squeezedtherefrom. In order to permit the rollers to be spread apart to clearthe head B while the attachment l is being pushed down for use or drawnup to an out-of-the-way position, I provide special means. The meanscomprises a pair of cords or cables I5. These are attached by connectingwires I6 which serve to join the respective pairs of brackets I3together as illustrated for example, in Figures 2 and 3. 'I'he upperends of the cables are attached to ears Il carried by a lever or latchI8. This is pivoted on the shaft I9mounted on an attaching collar 2o.The shaft is also provided with a pair of anti-friction rollers 2| overwhich the cable-ends pass as shown in Figures 4 and 5. This is merely torender the operation smooth and expeditious. It is evident that bycatching hold of thelever IS and pushing it down from the upstandingposition illustrated in`Figure 5, this exerts an endwise or upward pullon the cables. This action in turn, causes the carrier brackets for thewringer rolls to swing apart and in turn spreads the rollers. This issufficient to enable the rollers to clear the head B either as thewringer l is pushed down for use, or lifted up to an out-of-the-wayposition when not in use. Normally, the wringer attachment l is up andout-of-the-way. When, however, it is desired to bring it into use, onehand is wrapped around the mop handle C and the other hand grasps theknob 9. By forcing the knob downwardly while still holding the handle Cit is evident that the rollers I2 snap down Vover the head B and pressrmly against opposite sides of the mop A through the instrumentality ofthe compression springs I4. By still holding the knob 9 Y and pullingupwardly on the handle C, the mop A is drawn between the spring-pressedrollers I2 and the water is squeezed therefrom. During its upwardmovement, the mop A recedes into the receiver or cylinder II. When it isdesired to release the rollers I2, the latch IS is swung down to exertan upwardly pull on the cables and to spread the rollers apart in anobvious manner. Then the wringer 'I can be readjusted to its normalout-of-the-way position.

The purpose of the invention is obviously to provide a simple andexpeditious wringer attachment :for a mop handle which can be placed onthe handle and held in an out-of-the-way position under normalconditions without interfering with the use of the mop, and which may beput into position as shown in Figures 1 and 2 by the user for squeezingthe water from the mop.

It is thought that persons skilled in the art to which the inventionrelates will be able to obtain a clear understanding of the inventionafter considering the description in connection with the drawings.Therefore, a more lengthy description is regarded as unnecessary.

Minor1changes in shape, size and rearrangement of details coming withinthe field of invention claimed may be resorted to in actual practice,

' if desired.

Y Havingv thus described the invention, what is claimed as new is:

1. In a structure of the class described in com- `bination, an elongatedmop handle, a rnop swab secured to one end of said handle, a sleevelongitudinally slidable on said handle and adapted to receive said mopswab, a pair of brackets pivotally connected to the lower end of saidsleeve, a pair of substantially parallel rollers carried by saidbracket, said rollers being adapted to be positioned on each side ofsaid mop swab, resilient means normally urging said rollers together,and 5 cable means secured to each of said brackets for pulling saidrollers apart against the action rof said spring.

' 2. In a structure of the class described in combination, an elongatedmop handle, a mop swab l secured to one end of said handle, acylindricalshaped sleeve longitudinally slidable on said handle, andadapted to receive said mop swab, and being provided with a plurality ofapertures therein, a pair of brackets pivotally connected to l the lowerend of said sleeve, a pair of substantially parallel rollers carried bysaid brackets, said rollers being adapted to be positioned on each sideof said mop swab, resilient means normally urging said rollers together,and a cable connected to each bracket, and means for moving said cablelongitudinally of said handle for urging the rollers apart against theaction of the spring.

3. In a structure of the class described in combination, an elongatedmop handle, a mop swab secured to one end of said handle, acylindricalshaped sleeve longitudinally slidable on said handle, andadapted to receive said mop swab, and being provided with a plurality ofapertures therein, a pair of brackets pivotally connected to the lowerend of said sleeve, a pair of substantially parallel rollers carried bysaid brackets, said rollers being adapted to be positioned on each sideof said mop swab, resilient means normally urging said rollers together,and a cable connected to each bracket, and a pivoted lever on saidsleeve, the upper ends of said cables being operatively connected withsaid lever for urging the rollers apart against the action of thespring.
